1 claim. (CL 218-43) The invention relates to a heating 'element andmore especially to a removable electric heating element tor cookingutensils.

The primar-y object of the invention is the l 5 provision of a heatingelement o! this character,

wher-ein the same is in the form of a unit susceptible of beingseparably fltted to a cooking utensil, such as a coitee or tea pot, sothat by the removal of the element the utensil can be 10 moreconveniently cleaned without damage to the heating element during thisperiod.

I Another object of the invention is the provision of a heating elementot this character, wherein the make-up of the same is novel in form andcan be conveniently and easily attached to or removed from the cookingutensil, it being especially constructed for adaptability to a water,ooflee or tea pot.-

A further object of the invention is the provision of a heating elementof this character which is simple in Construction, thoroughly reliableand eflicient in its purpose, compact, strong, dui-able, and inexpensiveto manuiacture and install.

With these and other objects in view, the invention consists in thefeatures oi Construction,

` combination and arrangement of parte as will be hereinai'ter moreIully described in detail, illustrated in the accompanying drawing,which dis- 30 closes the preferred embodiment oi the invention, andpointed out in the claim hereunto appended.

In the accompanying drawing:

Figure i is a side elevation partly broken away of a coflee potshowingthe heating element constructed in accordance with the invention inelevation and applied to the pot.

Figure 2 is a tragmentary transverse sectional view through the heatingelement.

Figur-e 3 is a sectional View on the line 3--3 40 of Figure 2 looking inthe direction of the arrows.

similar reference characters indicate corresponding parte throughout theseveral views in the drawing.

Reierring to the drawing in detail, A designates generally a cookingutensil, in this ihstance indicative of e. ccflee pot, having thepouring spotit at ohe side and the handle 6 at the other side, the potbeing forme& witha unitary hollow 50 base l in which is accommodeted theheating element ccnstituting the present invention end hereinater fullydescribed.

The heating element comprises en msulating block 8, preierabiy ofcircular tor-m and housed within a caslng including the body portionhahet.

removable cover portion lo, respectively. The body and cover portions ofthe casing are semrably united through the medium oi a. screw li whichis passed centrally through the block 8 at the opening 52 provided insaid block.

Counterseated within the block 8 is the elee= trio heating coil sahaving the tine terminals l l which are fltted within the extension |5oi the block 8 and these terminals are engageable by a plug socket se ofconventional kind for the electric connection ll with a source o!current supply. The heating coil s, next to one ter- .minal lt, hasassooiated therewith a removable fuse i@ which is accessible on removalof the cover section i@ from the body sections oi th casing.

The body section 9 of the casing is formecl with a hanger ne cuttherefrom and this hanger is engageable with a ledge 20 formedinternally ot the base l of the pot A, while diametricany opposite thehanger and formed with the body section is a bolt barre! or housing !Icontaining the spring tensioned latching or looking bolt 22 which alsois adapted to engage with a keeper 23 internally oi the base 'i of thepot A so that the heating element can be removably held within the saidbase 'l of the pot, as is clearly shown in Figure 1 ot the drawing.

The latching or looking bolt has i'ormed therewith a finger mol 24 whichprojects through a suitable clearance in the bottom of the barrel orhousing :i and is readily accessible to a per son through the openbottom of the base l, so that the heating element may be readily andeasily released tor its removal ironi the pot. particularly whencleaning the letter, or tor other p p What is claimed is:

The combination with a cooking utensil having e, hoiiow portion et itsbottom and opening therefrom, of a heating element for removable flttingin the hollow portion and comprising e circular insulating block, acasing encircling said block and having a removable cover portion, anelectric resistance coil fitting said block and having terminal prongsextencled without the casing, a ledge iormed on the well of the hollowportion of said utensil, e, hanger cut from the casing and enggageablewith the ledge, and a looking bolt carried by the casing and engageablewith the well of the hollow portion oi the utensil, the wall oi thehollow portion of the utensil heing cut away to provide a clearahce forthe terminal prongs.
